title: Chromatographic analysis of new nonionic surfactants of oxyethylation products in the presence of calcium catalyst of rapeseed oil fatty acid methyl esters (RME).
abstract: Various methods of chromatographic analysis (GPC, HPLC, TLC) were used to estimate qualitatively and quantitatively the product of oxyethylation of rapeseed oil acid methyl esters (RME). The investigation enabled to evaluate PEG content in the product. The method of eliminating insignificant quantity of PEG found in oxyethylation products of n(TE) < or = 20 was presented. The data of thin-layer chromatography obtained in the course of research constitute a point of departure for calculating n(TE) content and HLB level.
